Hi,
I have a problem with a method call after a reinterpret_cats in a template class.
This is the code:
template <class Base>
class CComTearOffObject : public Base
{
public:
CComTearOffObject(void* pv)
{
ATLASSERT(m_pOwner == NULL);
this->m_pOwner = reinterpret_cast<CComObject<typename Base::_OwnerClass>*>(p
v);
this->m_pOwner->AddRef();
}
The AddRef call ends up in a segmentation fault. In the debugger I can see that the address of the function AddRef which can be found in the vtable is calculated wrong.
Has anyone ever had a similar problem? Or is something wrong with the cast?

Your testcase is a bit too short. Can you provide
a fuller, compilable testcase which demonstrates your
problem?
Thanks.
